摘要： Materials that contain liquid are deposited into grooves upon a surface of a work piece, such as a silicon wafer to form a solar cell. Liquid can be dispensed into work piece paths, such as grooves under pressure through a dispensing tube. The tube mechanically tracks in the groove. The tube may be small and rest at the groove bottom, with the sidewalls providing restraint. Or it may be larger and ride on the top edges of the groove. A tracking feature, such as a protrusion, Non-circular cross-sections, molded-on protrusions and lobes also enhance tracking. The tube may be forced against the groove by spring or magnetic loading. Alignment guides, such as lead-in features may guide the tube into the groove. Restoring features along the path may restore a wayward tube. Many tubes may be used. Many work pieces can be treated in a line or on a drum.

摘要： Patterned substrates for photovoltaic and other uses are made by pressing a flexible stamp upon a thin layer of resist material, which covers a substrate, such as a wafer. The resist changes phase or becomes flowable, flowing away from locations of impression, revealing the substrate, which is subjected to some shaping process, typically etching. Portions exposed by the stamp being are removed, moved, and portions that protected by the resist, remain. A typical substrate is silicon, and a typical resist is a wax. Workpiece textures include extended grooves, discrete, spaced apart pits, and combinations and intermediates thereof. Platen or rotary patterning apparatus may be used. Rough and irregular workpiece substrates may be accommodated by extended stamp elements. Resist may be applied first to the workpiece, the stamp, or substantially simultaneously, in discrete locations, or over the entire surface of either. The resist dewets the substrate completely where desired.

摘要： Semiconductor photovoltaic cells have surfaces that are textured for processing and photovoltaic reasons.

The cell also includes metallizations for collecting generated electrical carriers and conducting them away, which may be channels. The topography is considered during production, using a process that takes advantage of the topography to govern what locations will receive a specific processing, and which locations will not. Liquids are treated directly into zones. They migrate throughout a zone and act upon the locations contacted. They do not migrate to other zones, due to impediments to flow, such as edges, walls and ridges. Liquid may also be deposited and migrate within a zone, to block or mask a subsequent activity, such as etching.

摘要： Semiconductor photovoltaic cells have surfaces that are textured for processing and photovoltaic reasons. The absorbing regions may have parallel grooves that reduce loss of solar energy that would otherwise be lost by reflection. One form of texturing has parallel grooves and ridges. The cell also includes regions of metallization for collecting the generated electrical carriers and conducting them away, which may be channels. The topography is considered during production, using a process that takes advantage of the topography to govern what locations upon will receive a specific processing, and which locations will not receive such a processing. Liquids are treated directly into zones of the cell. They migrate throughout a zone and act upon the locations contacted. They do not migrate to other zones, due to impediments to fluid flow that are features of the surface texture, such as edges, walls and ridges. Blocking liquid may also be deposited and migrate within a zone, to block or mask a subsequent activity, such as etching.

摘要： A technique for removing loose powder from the interior surfaces of ceramic molds made using layer manufacturing processes, such as three dimensional printing processes. The interior of a mold is filled with water which is boiled and the particles are entrained in the flow caused by the boiling liquid. In another technique, the mold is immersed in water charged with CO.sub.2 and the pressure rapidly dropped to cause the CO.sub.2 to come out of solution as bubbles which eject the particles. Alternatively, fine particles are introduced into the mold and the mold is agitated to dislodge the particles and the powder so that they can be poured out of the mold. Such technique tends also to remove the surface finish of the mold. Any of the particles which remain can be dissolved in a liquid and removed in the liquid from the mold. Further, the surface finish of the mold can be improved by casting a slip of fine particles on to the surface to form a generally level, and preferably non-conformal, coating on the surfaces.

摘要： A technique for removing loose powder from the interior surfaces of ceramic molds made using layer manufacturing processes, such as three dimensional printing processes. The interior of a mold can be filled with liquid, such as water, which is boiled by applying microwave energy of a frequency selected to heat the liquid. The particles are entrained in the flow caused by the boiling liquid. Alternatively, fine particles are introduced into the mold and the mold is agitated to dislodge the particles and the powder so that they can be poured out of the mold. Such technique tends also to remove the surface finish of the mold. Any of the particles which remain can be dissolved in a liquid and removed in the liquid from the mold.

摘要： A pressure differential is applied across a mold sheet and a semiconductor (e.g. silicon) wafer (e.g. for solar cell) is formed thereon. Relaxation of the pressure differential allows release of the wafer. The mold sheet may be cooler than the melt. Heat is extracted almost exclusively through the thickness of the forming wafer. The liquid and solid interface is substantially parallel to the mold sheet. The temperature of the solidifying body is substantially uniform across its width, resulting in low stresses and dislocation density and higher crystallographic quality. The mold sheet must allow flow of gas through it. The melt can be introduced to the sheet by: full area contact with the top of a melt; traversing a partial area contact of melt with the mold sheet, whether horizontal or vertical, or in between; and by dipping the mold into a melt. The grain size can be controlled by many means.
摘要翻译：在模板上施加压差，在其上形成半导体（例如硅）晶片（例如，用于太阳能电池）。压差的放松允许晶片的释放。模具片可以比熔体更冷。几乎完全通过成形晶片的厚度提取热量。液体和固体界面基本上平行于模片。凝固体的温度在其宽度上基本均匀，导致低应力和位错密度和更高的晶体学质量。模板必须允许气体流过它。可以通过以下方式将熔体引入片材：与熔体的顶部完全区域接触; 穿过熔体与模板的部分区域接触，无论是水平还是垂直的，或者在其间; 并将模具浸入熔体中。可以通过许多方法控制晶粒尺寸。
